Thiol-capped CdSe quantum dots are synthesized rapidly in aqueous solution assisted by microwave irradiation without any poisonous materials. The growth rate of quantum dots is greatly enhanced in this current microwave synthesis. The narrow size distribution (~30nm) of CdSe quantum dots is similar to the oil samples. The results indicate that the photoluminescence quality of quantum dots is improved...
This paper presents an investigation on the fluorescent properties of semiconductor CdTe quantum dots (QDs) self-assembled on the surface of PVP (polyvinylpyrrolidone) capped silver nanoparticles (NPs) film by ligand field effect under the two photons excitation of 800nm femto second laser. A significant enhancement by 4.5-fold in the integrated fluorescence intensities, red shift of fluorescence...
